Objective:
This study investigates whether sexual minority patients have poorer treatment outcomes than heterosexual patients in England's Improving Access to Psychological Therapies (IAPT) services. These services provide evidence-based psychological interventions for people with depression or anxiety.
Method:
National routinely collected data were analyzed for a cohort who had attended at least 2 treatment sessions and were discharged between April 2013-March, 2015. Depression, anxiety and functional impairment were compared for 85,831 women (83,482 [97.2%] heterosexual; 1,285 [1.5%] lesbian; 1,064 [1.2%] bisexual) and 47,092 men (44,969 [95.5%] heterosexual; 1,734 [3.7%] gay; 389 [0.8%] bisexual). Linear and logistic models were fitted adjusting for baseline scores, and sociodemographic and treatment characteristics.
Results:
Compared to heterosexual women, lesbian and bisexual women had higher final-session severity for depression, anxiety, and functional impairment and increased risk of not attaining reliable recovery in depression/anxiety or functioning (aORs 1.3-1.4) and reliable improvement in depression/anxiety or functioning (aORs 1.2-1.3). Compared to heterosexual and gay men, bisexual men had higher final-session severity for depression, anxiety, and functioning and increased risk of not attaining reliable recovery for depression/anxiety or functioning (aORs 1.5-1.7) and reliable improvement in depression/anxiety or functioning (aORs 1.3-1.4). Gay and heterosexual men did not differ on treatment outcomes. Racial minority lesbian/gay or bisexual patients did not have significantly different outcomes to their White lesbian/gay or bisexual counterparts.
Conclusions:
The reasons for treatment outcome inequities for bisexual patients and lesbian women (e.g., 30-70% increased risk of not recovering) need investigation. Health services should address these inequalities. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
